Aak HN: What direction to take as a solo-dev?

I have been browsing the forum for tools/routes/frameworks as a solo-dev to take. I have seen people switch from PHP to Java and Spring Boot or people go from JAVA Spring Boot to .NET and Angular.

I wanted to ask other solo-devs who have tried different tools to the one that they are now, why did you switch and what makes it better than before?
